Starter with shock absorbing device

摘要

In a starter having a planetary gear reduction mechanism and a shock absorbing device, a first friction plate of the shock absorbing device is engaged with an internal gear of the reduction mechanism to restrict the internal gear from rotating. A space is provided radially between the internal gear and a housing to allow rotation of the internal gear upon application of an impact shock. A cylindrical member which is harder than the housing is disposed between the space relatively movably against the housing and the internal gear so that the internal gear is restricted from directly contacting the housing.
